One recent TripAdvisor traveler writes, "I've been to science museums before and none compare to this," and this seems to be a sentiment shared by many.

Everyone ages 4 and older pays the same admission fee (€15 EUR or about $20 USD) at NEMO; however, most visitors say their euros were well-spent. Kids, ages 3 and younger can enter for free. Also, the rooftop urban beach (complete with cafe) is free to visit. NEMO is open Tuesday through Sunday from 10 a.m. to 5:30 p.m. For more information, visit the NEMO website.
